Sen. Dianne Feinstein (D-Calif.) introduced a bill on Wednesday that would require vaccination, a negative coronavirus test or recovery from covid-19 to take a domestic flight.
EXPLAINER: She pointed out that air travellers coming to the United States from abroad already have to provide a negative test, even if they are travelling from countries with lower rates of transmission than many parts of the country. Starting in early November, restrictions on travel from 33 countries will fall as the United States moves to a new vaccine requirement for foreign visitors. Those visitors will also need to show proof of a negative test.
